2018-02-17 23:16:39 Christopher M. Rogers description Object to Path makes a bad conversion when offset is used on irregular shapes. To reproduce: 1. Open Inkscape (current trunk) 2. Draw a rectangle 3. Draw a circle overlapping part of the rectangle 4. Combine the shapes (Path > Union) 5. Path > Dynamic Offset 6. Drag offset handle inwards or outwards a bit 7. Path > Object to Path Result: Most of the nodes in the shape vanish, leaving only a small remnant of the original shape. Note: This works fine on two rectangles, so i assume it's something to do with miscalculating offsets on curved shapes. Tried two circles, and they vanish entirely!

Inkscape 0.92.0+devel+201802131923 on Ubuntu 17.10 0.92.0+devel+201802110719 was the version that I had before this version. I think that's when it was still working.
